I dunno about you, but i'm getting 4mp/tic back on celestials and 5 for carby/fenrir/diabolos just using a Fay Crozier and a right mix of perp/refresh gear, unconditionally too (except moonshade earring)... so if all you're getting is +2 with the TotM staves, you're overgearing perp.

And if I were to get a TotM staff at the current levels of perp cost, the only avatars it'll help with is the celestials, and I only really need to get a -4 perp staff to cap perp reduction (I'm not counting the spirits cos no one really cares, or its the same cost as celestials), so its still pretty wasted because of perp caps

As for the acc thing, acc gear on hands and legs are kinda wasted on regular melee attacks. For BPs, you shouldn't need to use them because of adequate skill to cover acc, and would likely move towards damage/crit/etc. In order words, the better you are, the less you'll need those 2 pieces. I no longer ever carry Evoker Spats on me
